Insert Row To SQL Server Using Visual Studio 2010 And ASP.NET

I am using Visual Studio 2010 with ASP.NET, VB, and using SQL Server as my database

I am creating a website using ASP.NET and I have a mailing list database, I have a add to mailing list page that takes in certain fields (Name, e-mail, phone number) that are TextBox and a sumbit button. When the submit button is clicked how to do I take the current values of those text fields and add them to the database.

I have done it using the DetailedView which works at adding to the database but I also want to redirect to a different page after inserting.

how to take the values from the TextBox and insert them into the database, or how to I redirect to a different page after inserting a new row with DetailedView.

Here is my code with for the .aspx file, it has both the TextBox's and the detailed view

<p class=whiteMail>
First Name: <asp:TextBox ID="FirstName" runat="server"></asp:TextBox> <br />
Last Name: <asp:TextBox ID="LastName" runat="server"></asp:TextBox> <br />
